Abstract

Transient structural information of matter can be obtained by time-resolved X-ray measurement, such as ultrafast X-ray diffraction (UXRD) and ultrafast X-ray absorption Spectroscopy (UXAS). A time-resolved ultrafast X-ray source is necessary for ultrafast X-ray spectroscopy measurements, such as XFEL or synchrotron radiation source. Because of the high cost of X-ray free electron laser (XFEL) and synchrotron radiation source, we designed a laboratory ultrafast plasma X-ray source driven by 800Hz high-energy laser. The X-ray pulse duration is shorter than 100fs. Copper was chosen as the target material of the source, and the expected photon flux can reach 10⁷ photons/s. The target material can also be replaced by other common target materials.
